IECUMIDIFZER Application filed June 2'0,

My invention relates to means for moistoning the air passing through theintake pipe that feeds the air to the carburetor of an internalcombustion engine.

One of the primary objects of my invention is to provide means wherebythe liquid from a fluid reservoir may be raised by capillarity out ofthe reservoir by means of a wick that extends into the air intake pipeso that the air moving past the saturated wick will take up moisturetherefrom and the moistened air fed to the carburetor. in thisconnection I have provided a member within the air intake pipe which isconstructed so that a channel or passageway is provided through whichthe air passing through tie intake pipe will be directed. This channelmay be provided by means of a hollow cylindrical member, or there may bea plurality of channels or grooves upon the exterior of the member, orbetween the member and the intake pipe, as shown in the specificallymodified structures herein illustrated. Other objects of my inventionreside in providing a moistening device of the above character that issimple in construcion,easy to install, will not r adily get out oforder, and which has features of novelty and dependability.

In the drawings 1 have illustrated a typical or preferred embodiment ofmy inven tion. in which Figure l is a side elevation showing myinventionattached to a carburetor air intake pipe.

Fig. 2 is a left hand edge view of the structure shown in Figure 1.

Fig. 3 is a. top plan of the aforesaid structure. Y

Fig. 4 is a detail of the wick and absor ent member removed from thepipe.

Referring to the drawings, 10 designates the pipe that is usuallyemployed for feeding air to a carburetor for an internal combustionengine and which is provided with an aperture 11 upon its side throughwhich the wick passes, as will hereinafter more fully appear. This pipe10, herein illustrated, is thewell known design employed upon a Fordmotor car and has a lateral upper end portion that partially houses theexhaust manifold of the engine so that the heat therefrom will raise thetemperature of the drawn-in air in order to avoid feeding cold air tothe carburetor after the engine has been started. I provide a fluidreser- OHIO.

voir in the form of a hollow receptacle 12 having a suitable lillinspout 13 that is closed by a screw cap l i. One end of the receptaclehas its longitudinal side wall formed with a depression or channel 15 ofsemi-circular shape that extends vertically thereof so that it isadapted to lit snugly around the adjacent portion of the air intake pipe10, while suitable clamping cars 16 are provided that extend outwardlyfrom the sides of this concaved or channelled portion and are drawntowards each other by means of a bolt and nut structure 17.

Immersed in the fluid in the receptacle 12 is an elongated wick 18 whichis of a capillary nature, and said wick is passed up wardly throughaperture 19 in the upper wall of the receptacle and then into the intakepipe 10 through the aperture 11 therein. l Vhere the wick is exposed tothe outer atmosphere, I have provided a shield or guard 20 that partlysurrounds the aperture 19 in the top of the receptacle and projectsupwardly, as seen in the drawings so as to protect the wick and, owingto its fragmental conical shape, it is adapted to shed otl' dust orforeign matter which might 0therwise come into contact with the wick andthereby hinder it in performing the functions for which it is designed.

Within the pipe 10 is an absorbent member 21 which may comprise aportion of the wick, or it may be a separate element that has intimatecontact with the wick so as to receive the moisture therefrom. In thepreferred embodiment of the structure this absorbent member 21 is of acylindrical shape and of an outside diameter approximately the same asthe interior diameter of the pipe so that it may be constricted slightlywhen inserted in the pipe in order to fit snugly therein. A centralpassageway 22 is pro-- vided entirely through the member 21 and thesides of said passageway are lined or faced with a reticulated metalwall or wire mesh screen 23, the function of which is to preventportions of the material of which the member or the wick is formed frombe ing drawn off by the air current, and thus to the carburetor where itmay clog some of the minute passagewaysv of needle-valve.

hat Iclaim:

1. A humidifier for the air supply pipe of a carburetor comprising aliquid-container removably clamped to said supply pipe, a wick having atubular formation at one end disposed within said pipe to permit air topass therethroug'h the reinainiiu portion of said wick being extendedthrough said pipe and into said container and iminersed in the liquidtherein, whereby the liquid is conveyed by capillarity to the interiorof said pipe and inoistens the air pa sing therethrough, and a shieldprotecting the portion of said wick between said pipe and saidcontainer.

2. A humidifier for the air supply pipe of a carburetor comprising aliquid-container renioyahly clamped to said supply pipe a wick having atubular ttorn'iation at one end disposed within said pipe to permit airto pass therethrough, a reticulated wall within the tuoular portion ofsaid wick and maintaining the same against distortion, the remainingportion of said wick being extended through said pipe and into thecontainer and immersed in the liquid therein, whereby the liquid isconveyed by eapillarity to the interior of said pipe and inoistens theair passingtherethrough, and a shield protect ing the portion of saidwick between said pipe and the container.
